What's included
5 deliverables in this treatment
- 276 allergen targets tested: 150 native extracts + 126 molecular allergen components
- Single blood draw — no repeated testing or multiple appointments
- Identification of primary sensitisation vs cross-reactive IgE patterns
- Analysis in VIDIA immunology laboratory (GENNET/VIDIA partnership)
- Results via patient portal with allergen sensitisation map
VIDIA DIAGNOSTIKA offers the ALEX (Allergy Explorer) multiplex allergy test — one of the most comprehensive commercially available molecular allergy diagnostics — at 6,500 Kč through its immunology laboratory operated in partnership with GENNET. ALEX simultaneously measures specific IgE reactivity to 150 allergen extracts and 126 purified molecular allergen components in a single blood sample, providing a complete allergy sensitisation map that identifies both genuine allergies and cross-reactions. It is particularly valuable for patients with multiple apparent allergies who need to identify the primary sensitiser.
About this treatment
The ALEX (Allergy Explorer) multiplex allergy test at VIDIA DIAGNOSTIKA represents the broadest single-blood-draw allergy investigation available in the Czech private laboratory market. At 6,500 Kč, it covers 276 distinct allergen targets — 150 native allergen extracts and 126 purified molecular allergen components — in a single serum sample processed in VIDIA's immunology laboratory.
Conventional specific IgE testing examines one allergen at a time (350 Kč per extract at VIDIA). Building a comprehensive allergy profile this way requires many separate tests and, at 350 Kč each, quickly becomes expensive and logistically fragmented. ALEX tests all 276 targets simultaneously from a single blood draw, costing less than 24 Kč per target — a dramatic cost-efficiency advantage for patients with complex or polysensitised presentations.
Molecular component-resolved diagnosis (CRD) — the discipline that ALEX is built on — distinguishes between genuine primary sensitisation and IgE cross-reactivity. Many patients believe they are allergic to multiple unrelated allergens when they are actually monosensitised to a single primary allergen whose molecular epitopes appear in several sources. For example, a patient reacting to birch pollen, apple, hazelnuts, celery and carrots may be primarily…

Who is this for?
Patients with multiple apparent food or environmental allergies, those considering allergen immunotherapy, patients with unexplained anaphylaxis, polysensitised individuals needing a comprehensive sensitisation map
Preparation required
No fasting required. Attend any VIDIA collection site or the Praha 7 GENNET site with a physician referral form and health insurance card. Bring a list of previously identified or suspected allergens to share with your physician when interpreting results.

Biomarkers tested
5Immunoglobulin E (IgE) is a protein associated with allergic reactions that is normally found in very small amounts in the blood. IgE functions as part of the body's immune system (its defence against 'intruders').
Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.
Imbalances in gut pH influence short-chain fatty acid production and their effects.
